The document discusses various methods of applying fertilizers, including broadcasting to spread fertilizers uniformly, top dressing nitrogen fertilizers for closely sown crops, and placement methods like plough sole placement, deep placement, and localized placement. Other methods covered are drilling fertilizers in the same row but at different depths for cereal crops, side dressing between rows and around plants by hand, and band placement in hills or continuous bands alongside rows. The document also discusses pellet application for paddy crops, liquid fertilizer application through starter solutions, foliar application of minor nutrients, fertigation by injecting fertilizers into soil under pressure or non-pressure, and aerial application.

3. Broadcasting (Basal application)
 To spreading fertilizers uniformly
 Dense stand roots
 large doses
 Rock phosphate

4. Top dressing
 Particularly nitrogenous fertilizers
 Closely sown crops

5. Disadvantages of Broadcasting
Nutrients cannot be fully utilized
Weed growth is stimulated
Nutrients are fixed in the soil

6. Placement
Placement of fertilizers in soil
The most common methods of placement are
as follows:
i. Plough sole placement
ii. Deep placement
iii. Localized placement

7. Drilling
 Same row but at different depths
Cereal crops

8. Side dressing
Between the rows and around the
plants
By hand

9. Band Placement
Two types of Band Placement
Hill placement
 Close or both sides
Row placement
 Continuous bands on one or both sides of
the row

10. Pellet application
 2.5 to 5 cm
 1:10 Ratio
 Paddy crops

11. Methods Of Applying Liquid
Fertilizers
Starter solutions
 N, P2O5 and K2O
 1:2:1 and 1:1:2
The disadvantages of starter solutions are
 Extra labour is required
 The fixation of phosphate is higher

12. Foliar application
 One or more nutrients
Advantages
 Nutrients absorbed by leaves
 For minor nutrients
like iron, copper, boron, zinc

13. Fertigation

14. Injection into the soil
Two types of Injection
Non pressure Type
 On surface or in furrows
Pressure Type
 In furrows
 12-15 cm

15. Aerial application
